VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 297,834, dated April 29, 1884.

Application filed August 10, 1883. (No model.)

To all whom it may concern.-

Be it known that I, SOLOMON E. OVIATT, of Lansing, county of Ingham, State of Michigan, have invented a new and useful Improvement in Vehicle-Springs; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art-to which it pertains to make and use it, reference being had to the accompanying drawings, which form a part of this specification. I

My invention consists in the combination of devices and appliances hereinafter specified, and more particularly pointed out in the claims. i

In the drawings, Figure 1 is a side elevation of a device embodying my invention, showing parts in section. Fig. 2 is a vertical section of the same, showing parts in elevation. Fig. 3 is a separate view of one of the parts. Fig. 4 is a view of another of the parts.

My invention relates to vehicle-sp rings, and has for its object an improved construction of the springs, the method of their attachment, and the general operation of the parts, so as to provide a strong, elastic, and economical Spring. I

In the drawings I have illustrated the device as applied to vehicle-seats; but I contemplate its use also as a side or cross spring applied to vehicle-bodies, as it is adapted for general use as a vehicle-spring.

In carrying out my invention, A is a vehiclebody. B is the seat.

O is the riser, to the top of which the seat is secured. This riser may be of any desired length and form, preferably constructed, as

shown, with a central standard, having suitable arms at the tops for securing the same effectually to the seat. This riser is constructed at its base with suitably curved and flanged extensions, braces,.or supports Oand O".

D is a spring, bent midway of its length, as shown, and adapted to. fit suitably into the corresponding recess in the riser, when it is secured in place by abolt,'E, extending through the flanges of the riser, as shown. It will be observed that the spring is thus secured to the riser without any bolt-holes being cut therein to weaken or impair its strength.

F is a cushion,which may be located between the bolt and the spring, or it may be located above the spring, between it and the riser. This cushion may be used or dispensed with at pleasure. Its use adds firmness to the device. The ends of the spring are provided with clasps G, adapted to' engage upon the edge of the vehicle-body. At one end I prefer to use a suitable roller, g, adapted to carry the spring without friction as it is caused to travel upon the, edge of the body."

H-is a hinge similar to that combined with the riser in a patent of the United States granted to me June 27, 1882, No. 260,313. This hinge is secured to the front end of the spring, the construction being such that the seat may be thrown forward, if desired. I desire to use the spring either with or without this hinge. I prefer,also,to locate underneath the clasp at the front end of the spring a block of rubber, g, or other suitable material,to elevate the spring should the hinge not be employed approximately on a level with the roller 9 at the opposite end, and also to prevent the slipping of the spring at this end, making the roller g do all the work as the spring is extended or retracted.

I prefer to so construct and adjust the sweep of the spring in its relation to the braces c and c of the riser, that when there is no pressure upon the-seat there will be a space between the spring and the ends of the braces,as shown in Fig. I at c. It will be observed that the construction and arrangement are such that when weight is applied to the seat the ends of the braces c and 0* will gradually be brought down upon the spring, thus giving to it increased strength. The sweep is thus shortened by the addition of weight, while it is also lengthened as weight is removed, making a veryeasy seat for a person of light weight and a correspondingly strong and easy seat for one or more persons of heavy weight. It will be observed that the closing of the braces o and 0" upon the spring under pressure will be gradual and proportioned to the weight.

Serious difficulty has heretofore been expe rienced in the use of vehicle-seat springs from the lateral motion and strain upon the springs on rough roads, the strain being communicated to the ends of the springs, frequently causing them to break; but it is an important feature of my improved spring that this tend- I 3.
